    Plan expansion works for a new Gate House and refurbishment of the existing Gate House to accommodate Enhanced Gate Security.

    Verbatim wording from the response

    “HMP & YOI Parc is designated a Category C prison, and as such, was not originally funded or risk assessed to provide full Enhanced Gate Security. Increased and changing security challenges, including those enabled by technological advancements and changes to the make-up and nature of contraband items, have led to agreement by HMPPS that the prison should now be funded and risk assessed for Enhanced Gate Security, and the Director has, since June 2024, prioritised addressing identified requirements in Enhanced Gate Security provision.”

    Use specialist screening equipment routinely to screen staff, professional visitors and social visitors entering the prison.

    Verbatim wording from the response

    “The conventional scanning equipment which is part of the traditional Enhanced Gate Security model will be installed within the new Gate House building once it is constructed. Pending construction of the new Gate House building, G4S identified a solution to the current logistical restriction by purchasing specialist technological equipment, similar to the latest equipment used in some airports. This equipment is now routinely used to screen staff, professional visitors and social visitors coming into the prison. HMP & YOI Parc was the first prison in the UK to deploy this technology, following a review of best practice across other sectors.”

    Expand the Special Searching Team to increase the frequency and quality of staff and visitor searches.

    Verbatim wording from the response

    “Enhanced Gate Security is provided by a range of additional tools and measures which are already being used at HMP & YOI Parc. Bag scanners and handheld metal detectors are routinely used by staff to support improved searching when visitors and staff enter the prison. The Director has expanded the size of the Special Searching Team, significantly increasing the frequency and quality of searches, and there are now an average of approximately 1,700 staff entry and exit searches per month, which represents a significant increase compared with 2022. This compares favourably with the majority of establishments within the prison’s comparative prison group. G4S has funded additional external dog patrols which have worked to significantly reduce the number of throwovers experienced at HMP & YOI Parc.”

The significant cost of the replacement works (each replacement window unit costing in excess of £3,500) is being shared by HMPPS and G4S. A timetable for the replacement programme has been agreed with the Authority.”

    A temporary gatehouse extension was not pursued because existing interim searching measures were considered a better use of finances, though less comprehensive.

    Verbatim wording from the response

    “G4S previously submitted a proposal to HMPPS for a temporary extension (modular building) to accommodate Enhanced Gate Security. Understandably, this was not seen as the best use of finances since the local team had introduced interim measures to support and enhance the searching of staff and visitors, albeit not to the same level of searching achievable with Enhanced Gate Security provision. Any changes to the design of the building must be approved and funded by HMPPS.”

    Window replacement cannot be completed widescale or faster because approved suppliers, specialist contractors, prisoner relocation and security logistics constrain delivery.

    Verbatim wording from the response

    “Practical issues dictate the speed at which window replacement works can be achieved. The windows, by their very nature and purpose, require specialist manufacture and there are a very limited number of HMPPS approved suppliers manufacturing the windows to the requisite specification. Such suppliers are in demand, not only in relation to manufacturing replacement windows for existing prisons across the nationwide prison estate, but also manufacturing windows for new establishments currently under construction.”

    PFD Monitor interpretation

    Easy availability of mobile phones in prison

    Wider context from the report

    “It is of grave concern that: (1) New psychoactive substances, especially ███, are easily available in HM Prison High Down, as in many other prisons in England & Wales a. New psychoactive substances are dangerous illegal drugs of abuse (there is no clinical or medical use for them) and they are responsible for the death of a prisoner in England and Wales about every 5 days b. Prisoners are coming into prison without a drug habit and develop a drug habit in prison due to the ease of their availability c. Vulnerable prisoners are being forced to test new batches of illegal drugs coming into the prison (2) Mobile phones are easily available in HM Prison High Down, as in many other prisons in England & Wales a. The access to mobile phones facilitates prisoners’ conduct and finance of drug dealing, including the arranging for the delivery of drugs by drones to precise locations at specified times b. The access to mobile phones allows sharing information (including photographs and videos) across not only High Down prison, but across other prisons in England & Wales, presenting safety and security risks c. The access to mobile phones facilitates the highly lucrative, damaging and dangerous activities of the organised criminal gangs working in HM High Down, and other prisons in England & Wales (3) The use of ███ in HMP High Down, as in other prisons in England & Wales, presents a serious risk to prison safety and security a. ███ facilitate the delivery of drugs into prison to precise locations at specified times b. ███ can be used to bring in other contraband including weapons and even firearms c. The increasing sophistication of ███ (and their increasing payload) increases the risks and dangers to life (4) The Ministry of Justice advised the court that it does not hold statistics on drug-related deaths in prisons in England & Wales. Basic risk management requires risks to be quantified and assessed in order that they can be addressed. You cannot properly manage that which you do not measure. ”

    Invest over £40 million in physical security across 34 prisons, including anti-drone measures at more than 15 priority prisons.

    Verbatim wording from the response

    “HMPPS is aware of the available routes for contraband, such as drugs and mobile phones, to enter prisons and how they are influenced by factors such as security measures, geographical location and prisoner cohort. Due to this, our approach to conveyance is multi-faceted. In the 2025/2026 financial year, HMPPS is investing over £40m in physical security measures across 34 prisons, including £10m on anti-drone measures, such as window replacements, external window grilles and specialist netting in over 15 priority prisons.”
